In this paper, we investigate the transport properties of microwaves in a two-dimensional (2D) graphenelike photonic crystal (PC) slab. We realize a narrow electromagnetic (EM) beam by using a grounded coplanar waveguide with better direction, which is beneficial to the study of the transport properties of (2D) PCs. The extremal transmission of the microwave near the Dirac point in a graphenelike PC slab, being inversely proportional to the thickness of the sample, is demonstrated by means of numerical simulation. Furthermore, we verify experimentally that some certain EM field modes for photonic bands cannot be excited in the PC slab.
